We appreciate your report but I was not able to reproduce this issue:

Tested on:
• Browser / Version: Firefox Release 125 (2016013951-🦎125.0-20240408174943🦎)
• Operating System: Samsung A51 (Android 11) -1080 × 2400 pixels 20:9 aspect ratio (~405 ppi density)

Suggestions:
• Clear cache/data/cookies, disable Ad-blocker (if available), or create a new profile (without syncing/importing data) and check again
• If there are any changes made to the default settings of the browser (e.g. in about:config), please revert to the default settings

As you can see in my attached video, there needs to be more text so that we can scroll the page and that's when you see that glimmer of the logo. You should also see "YouTube history is disabled" and "Search to start" displayed on the page and the "Scroll to hide toolbar" setting enabled. Can we have a look?
